I dunno. Some I agree with, others seem to be poorly-differentiated shades of the same subgroup. Neoconservative in particular is a term that means different things to different people, and given the collapse of the USSR ended serious global threats of Communism as a force almost two decades ago, this particular definition seems pretty dated. I think of most Conservatives as falling into three main types with a variety of sub-flavors:
Libertarian - Your basic limited government, RKBA, "Leave me alone" guys.
Social Conservatives - Evangelicals, Right-to-Life, and other people who look to moral/religious principles first rather than legal/analytical ones.
Fiscal Conservatives - The RINOs who run the GOP, and who really have more common ground with the Dems on social and individual rights issues than they do with the Social Conservatives or Libertarians. They are mainly 'Conservative' only in wanting to keep the Government hand out of their family trust fund or personal investments, so their preference for lower taxes has a largely-coincidental effect of looking like they want Small Government. They really don't, what they want is just low taxes. Collectively, they couldn't really give a rat's ass about the Social or Liberty issues. In fact if they see any of them as economically expensive, they'll sell them out in a heartbeat. Neocons are a subgroup of this bunch, mainly identified by also being for aggressive foreign policy initiatives, despite the tax load that entails.
